Application filed August 5, 1902. Serial no. 447,107.

To all whom it may concern:

Be it known that "I, THOMAS N. Fusions,

a citizen of the United States, residing at San 7 Francisco, in the county of San Francisco and State of California, have invented certain new and useful Improvements in a Com- 5 bined Washtub and Sink; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it a pertains to make and use the same.

T is invention relates to combined washtubs and sinks, and moreparticularly to a nection with the waste-pipe. Fig. 3 is a destructure of the character referred to especially adapted for use as an inside fixture for kitchens where economy of space is a desideratum, particularly in apartment houses or flats.

The invention vwill first be hereinafter more particularly describedwith reference to the accompanying drawingawhich are to be taken asa part of this specification, and then pointed out in the claims at the end of the description.

In said drawings, Figure 1 re resents a vertical longitudinal sectional e evation of a combined Washtub and sink embodying my invention; portions of the tub and sink being broken away to avoid the necessity for illustrating the full length of either. Fig. 2 is a detail view partly in section ofa chamberat the bottom of the washtub showing its contail view partlyv in section of a portion of the overflow pipe and circular chamber at its top. Referring to said drawings, in which the same reference letters are used to denote corresponding parts in different views, the letter A may denote a washtub 40m? reinforced cement mo ded in I one piece with anjordinary porcelain enameled sink B.

referably formed embedded in the cement duringthe process of. molding, as will be understood by those skilled, in the art to latcs.

The letter C denotes a suitable chamber, which may be of cast-metal, also embedded in the cement bottom of the tub, and having an open top-provided with a top plate or cover 0 having a suitable aperture therein to receive a thimble D through which the liquid contents of the tub may flow into said which the invention retubular threaded the nipple to provide an intervening space to V chamber. The cover 0 is preferably 7 rovided with marginal ribs or 1 anges e W 'ch overlap the sides or upper edges of the chamber G, and the latter has a lateral tubular extension C which is interiorly screw-threaded to receive a short exteriorly threaded sleeve E. The cover 0 may terminate short of said ortion .or extension 0' of receive the lower end of an overflowp pe .or tube F embedded in the cement wall dividing the tub. and'sink, said tube being preferably elliptical or oval shaped in cross-section and made of zinc to prevent corrosion. A circular or other suitable chamber f ma be soldered or otherwise secured upon t e upper end of said overflow pipe and provided with a perforated disk or guard late F; As shown, the overflow ipe and t e inlet chamber thereon are em edded the cement moldin forming the solid Wall. between the washtu and sink but a different arrangement might be employed without departing from thespirit and scope of my invention.

is placed'a rubber or'other suitable washeror gasket; 1, and, referablfi,

protect the 111 her was er or gasket from grinding away while tightening up the joint.

At its upper end the elbow section of the dis charge pipe ;G is provided with a flared end 9" conforming in shape to the downwardly a brass ring 45, to'

flaring protuberance-or nipple K on the vbottom of the sink, and 'betweenthese flaring .portions may be placed a of putty 1c,

such as ordinarily employed in connecting sinksto waste-pi es. v, preferabdy formed with a lar'pipe like.

w aeptpe- The chamber is circular bottom hav terminal fcrccnnection with t around the porcelain-lined sink is liable to as shown.

' and also having upperend flared and ntted over or upon said pipe-like end or bottom of the chamber 0, a correspondingly shaped r ng M thereon adapting. it to be screwed up tightly against the angular terminal of the chamber C so that the endof the lead pipe will be spread out to form a secureconnection and water-seal between the two parts,

which may be secured together by means of bolts Nv passed through apertured lugs n and respectively, I

m on the chamber '0 and ring'M,

On account of the unegual expansion. and .contractlon of cement an metal, the cement crack as it hardens or sets, and to avoid this difiiculty, and at the same time to adapt the sink to be easily removed when damaged and to. permit another-sink to be substituted 1n its stead, without injuring or damaging other parts of the structure, 1 may place between the cement body and the outer sink a layer or layers of soft material, such as felt, between layers of water-proof material, preferably tar-paper, as at 0, thus forming a cushion on which the sink is seated and which will yield sufficiently during the shrinking process to prevent the cement from cracking, and being firmly embedded in the cement the sink ma be easily removed and re laced without adecting the cushion or ot er parts of the structure. The waterproof material prevents-the moisture in the cement, which always seeks the surface, from eva orating 'too-quickly and thus conduces to t e formation of a more com act body of cement without crack or blemish resulting which will occupy but a smal from the shrinkage.

I thus provide a very sim 1e and efficient strong anddurable combine wash-tray and sink, without lead-pipe wi ed joints and l space and may be manufactured at a comparatively smal cost. s

It will be understood, of course, that various changes may be made in the form and arrangement of the parts, and in the materlal used, without departing from the prmciple and scope of my invention, and hence I do notdesire to be restricted to the specific construction and arrangement of parts shown or described.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent of the United States is:
